    That got me thinking: couldn’t that be solved by adding a layer in fron akin to a phosphor screen which “buffers” the light a bit thus bridging the switching which should reduce flickering?

      Not without losing brightness. White LEDs work that way and are less bright than an uncovered LED of the same power. Some of the light from the LED becomes waste heat instead of light when the phosphor absorbs it.

      Also, not without losing response time. Part of the point of using LEDs for displays is that they can change brightness very quickly.

          That’s a good point, I don’t remember much ghosting on those. I guess it might depend on the phosphor used. If it was tuned to only fluoresce for that imperceptible off time and no longer it would probably work.

          I guess it’s a similar idea to quantum dots, but if those quantum dots fluoresced for just a bit longer.
